Estimated accumulated snowfall water equivalent at 1500 m

A 15-day proof over every native ECMWF grid cell inside the alpine frame, each one sampled independently. It uses the same pressure-aware wet-bulb snow-level method as the resort charts.

Liquid equivalent—not snow depth. Derived precipitation phase at a virtual 1500 m surface. It is not settled snow-base depth and does not model compaction, melt, wind transport or pre-existing snow.
